* If undergoing surgical resection, has submitted a tumor tissue sample during Screening.
* Has adequate organ function.
Exclusion Criteria:
* Has a known additional malignancy that is progressing or has required active antineoplastic treatment (including hormonal) or surgery within the past 3 years.
* Has had esophageal or gastric variceal bleeding within the last 6 months.
* Has clinically apparent ascites on physical examination.
* Has had clinically diagnosed hepatic encephalopathy in the last 6 months.
* Has received local therapy to liver ablation other than with radiofrequency or microwave ablation.
* Has a history of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
* Has an active infection requiring systemic therapy.
